Problem with a deleted subscriber - who payed AFTER being deleted

Hi there,

I've got the following problem :

An user registred for a subscrpition in april, but had a problem with paypal and did'nt finished the subscription process.
At this time he was added to my database as an user but not a subscriber.

After a while, I accidentaly deleted this user.

But some days a go he decided to pay for his subscription. I can track him in paypal, but he does'nt exist in wordpress - and of course cannot access to his paid content.

What can I do to fox that ?

He choosed to pay monthly his subscription. Is there also a possibility for me to give him a discount ? ( like one month for free ?)

Many thanks for your help.

Best,
Yan
